I think this is completely delightful in flavour but unbalanced vis a vis sweetness. I added 1/4oz gin and that took the edge off. Am looking forward to trying this with a dry vermouth to see if that tempers things. As it stands, the vermouth is pretty shy and retiring in this drink.

Much as we love Yellow Chartreuse, in this instance we reduce it to 20ml and up all other ingredients to 25ml. No offense to the good monks...all things in moderation, as perhaps they would agree. Although Mr Wilde had another view on that subject which maybe the monks smile at when it comes to their tipple.

Our new favorite

Very nice. The subtle flavours of the yellow chartreuse adds an additional herbal taste to the gin base. Lemon did add a hint of citrus which was very refreshing.
Do think the 9 rating of dryness is a bit high. I would say a 7 or 8. Our lemons were tree ripened so that may have added to the sweetness.
